Data Transfer between Two Pendrives Using Raspberry Pi

Now a day's portability is most important. So to achieve this, we are designing such a system which can carry anywhere. Using this system we can not only transfer the data but also we can see the transfer of the particular file which we want to send by using LCD display. Now a days to transfer data between two pen drives,, we use PC or laptop, but it is not always possible to carry such a large device only for the data transfer. So to overcome this problem we design a system which is more compact. In our project we are transferring the data between two pen drives without using any computers or laptops. As shown in the block, whenever we insert two pen drives in to the USB port of Raspberry Pi, this can be done by giving the command to the processor. The processor indicates that the pen drive is inserted successfully till the user cannot send any command to processor, the operation does not start. After sending the particular command to processor, it will start fetching the data from source pen drive into buffer and the ARM processor wait for the signal from destination pen drive. When the processors get the signal from destination pen drive, the data transfer operation begins. Only the ARM processor should get the external hard key input signal from the user. Once the user press the hard key the ARM processor get the information to transfer the data between two pen drives. While transferring the data the LED blinking rate will be increased, when data transfer is completed then LED will stop blinking. This total operation is performed on the Raspberry Pi board by using a “Raspbian wheezy” operating system.
